What to consider when choosing an alarm with Reformia
The average cost of installing an alarm in homes can range from 200 € in apartments to 350 € in single-family homes. To this you would need to add the monthly fee if it's connected to a monitoring center, which is around 30 €-40 €.

1. Purpose of the alarm
The type of alarm will depend on whether its goal is simply to deter or to achieve higher levels of protection against intruders. In the first case, an alarm without monitoring center connection may be sufficient, but in the second case, this aspect is important.

2. Entry points to the house
These are important because they should always have a detector. In the rest of the property, it may be sufficient to install detectors in hallways or passage areas. However, access doors, garage doors, or exits to patios and gardens must be well monitored.

3. Location of the home
Protection levels can vary depending on the type of property. Therefore, if it's an apartment, the type of alarm can vary depending on the floor, since ground floors and top floors are more vulnerable to break-ins. It can also be different in isolated houses compared to semi-detached houses or apartments with adjacent terraces.
The average cost of installing an alarm in homes can range from 200 € in apartments to 350 € in single-family homes. To this you would need to add the monthly fee if it's connected to a monitoring center, which is around 30 €-40 €.

1. Hire a specialized company
Although all types of alarms are commercially available, it's always advisable to consult professionals. They are the ones who know all available systems and in which cases some are more advisable than others. They also know the weakest points and how to protect them properly according to the level of security desired. It should always be an authorized company.

2. Request a home security assessment
The next step is to conduct a thorough assessment of the home: location, environmental security, weak points, interior layout, and perimeter if it's a house, etc. These questions will determine the most suitable type of alarm, as well as the number and placement of detectors.

3. Installation of the alarm system most suitable according to the security assessment
This is the last step and the most important. It's not just about installing the control panel and detectors in the right places, but about verifying that the entire home is indeed monitored and there are no blind spots.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of property
Apartments are typically more affordable (200-250 €) than single-family homes (300-350 €) due to the larger surface area and increased wiring complexity in the latter.
Number of sensors and control points
Each additional motion, door, or window sensor increases costs by 30-50 € per unit, with larger homes or those with multiple access points requiring more sensors.
Connection to alarm monitoring center
If you want 24/7 professional monitoring, installation can increase by 50-100 € more, plus a monthly fee of 30-40 € that varies depending on the company.
Installation complexity
Homes with older structures, difficult-to-drill materials, or multiple floors require more labor time, increasing the final budget by 100-150 €.

There are many factors that influence the price of installing alarms in a home. On one hand, you need to consider the size of the home and the number of floors if it's a single-family house. The number of detectors also matters, as well as whether perimeter surveillance is needed. Another factor is the level of security and the type of alarm chosen. And finally, you need to consider whether it's an alarm with monitoring center connection or not.
Advantages of installing a home alarm
The average cost of installing an alarm in homes can range from 200 € in apartments to 350 € in single-family homes. To this you would need to add the monthly fee if it's connected to a monitoring center, which is around 30 €-40 €.
- Hiring an alarm with monitoring center connection, two motion sensors with camera and one infrared sensor, the cost can reach around 30 €. If there are four cameras, the price will be between 40 €-50 €, depending on the company.
- The installation cost usually ranges from 50 € to 100 €, plus the equipment, which typically costs around 250 € in apartments and 350 € in houses.
- A no-fee alarm system with two motion detectors and 9 door or window sensors can cost around 200 €.
A good lock is not always enough to prevent break-ins. Installing an alarm in your home is one of the best protections, as it not only warns of the problem, but if connected to a monitoring center, the police will be notified.
Serves as a deterrent to thieves
Installing an alarm in your home is a protective measure, but just the warning signs or cameras alone have a high deterrent effect. Thieves will always look for easier targets.
